Original application filed October 7, 1916, Serial No. 124,405. Divided and this application filed September 2, 1921.

To all whom it may concern:

Be itknown that I, Gnone SoHwAeAoH, a

Sch. 48,294V/2 1G, and ay-28,. 1915, No. Sch. 48.656V/24G, and May 29, 1915, No. Sch. of which the following is a specification. This invention relates to apparatus for removing material to be dumped, particularly hot ashes, clinker, coke, dust and the like from furnace installations, boiler plants, coke-ovens, refuse destructors, feed heaters and .like plants. In the parent application, Serial No. 124,405, filed October 7, 1916, Patent No. 1,399,663, December 6, 1921, from which this has been divided out, some vention aredescribed which are particularly adapted for continuously conveying away large quantities of quenched material in a long tank or channel to a place remote from the discharge pipe.

A. primary object of this invention is to provide rotary conveying apparatus particularly adapted .for use in connection with small plants, in which the quenched materialis to be removed directly at the place To this end I arrange in the tank directly at the mouth of the discharge veyor wheel p aced slantwise relatively to the surface of the water in the tank.

The invention consists in the construction, arrangement and combination of parts de- Berlin, Germany,

the like. The wheel or rotary scraper Z comprises scrapers or blades or arranged at intervals which push the material up the slanting bottomof the tank at until it falls over the edge 0 of the tank located above the level I) of the water, whereupon it is conveyed away by suitable transport devices such as tilting wagons, conveyor belts or the like, not shown. The blade wheel or rotary scraper Z need not necessarily work directly on the bottom of the tank a. If desired, the axle m of the wheel may be so arranged between the wheel Z and the bottom of the tank. I

The described apparatus is particularly suitable for removing the material from the water close to where it enters, or when the material is discharged through only one p p An important feature of the apparatus is that it comprises no immersed joints, pivots or other delicate parts subjected to excessive wear and tear.

It may be mentioned, in addition, that any water removed with the wet ashes or clinker will be replaced in .order that the end of the pipe 0 may always be sealed by the water in the tank.
